WING JOINER INSTALLATION
1. Using the wing joiner assembled in Step 1 of pre-assembly, insert
the wing joiner into the wing panel temporarily. Also install the wing
#43 alignment peg as shown. Do not glue at this time.
CAUTION:
Make sure that the glue joints at the wing root are fastened
securiy. Check the ribs and the sheeting. If this is at all loose, apply
epoxy between the rib sheeting and spars.
4. When you are satisfied with the fit of the wing joiner, remove the
wings from the joiner. Mix a batch of 30 minute epoxy and using the
right wing panel (has Hobbistar on top) smear the inside of the right
wing joiner pocket with a heavy coat of epoxy. Also coat half of the
wing joiner with epoxy and push into the wing joiner pocket. Coat half
of the wing alignment peg with epoxy and insert it into the hole at the
rear of the wing root. Clean the epoxy from the wing root to prevent
epoxy build up. Allow the epoxy to cure.
2. Slide the other wing panel onto the wing joiner. Slide the two wing
halves together. Check for proper alignment. There should be no
gap between the wing halves. If there is, trim the end of the wing
joiner slightly to allow proper fit. Do not glue at this time.

5. Mark the location on the bottom of the wing where the wing joiner is
installed.
3. The wing should form a "V" when assembled as shown. The top of
the wing has lettering on it. When one side is placed flat on your
work surface, the other wing tip should be angled up so there is
approximately 2" of clearance between the surface and the tip.

6. When the epoxy has cured you may proceed to join both wing panels
together. Mix a batch of epoxy and heavily coat the wing joiner
pocket of the left wing. Also apply an even coat of epoxy on both wing
roots. Be sure to cover the whole wing root. When satisfied with the
gluing, slide the wing panels together and check for fit. Wipe excess
glue from the joint. IsopropyI alcohol works well for this. It is best to
use masking tape to hold the wing halves together until the epoxy
cures.
